Use Case

As a... driver engineer
I want... sessions and transactions to support CSOT
So that... the driver can have full CSOT support

User Impact

• N/A; new feature

Dependencies

• Required to release CSOT

Unknowns

• questions that need to be answered to determine implementation

Acceptance Criteria

Implementation Requirements

• Add defaultTimeoutMS option to ClientSession and support timeoutMS for:
  • commitTransaction
  • abortTransaction
  • withTransaction
  • endSession
• Ensure that if defaultTimeoutMS option is not specified, it inherits from parent MongoClient
• Ensure that if timeoutMS is set when calling session.withTransaction that the timeoutMS value is applied to the entire withTransaction call
• Ensure that when an explicit session with a timeoutMS value is used, a MongoAPIError is thrown if timeoutMS is also set at the operation level for operations that are part of a withTransaction callback
• Ensure that timeoutMS is refreshed for the abortTransaction operation if the withTransaction callback errors and the transaction must be aborted

Testing Requirements

• Unskip spec tests in following files
  • sessions-override-operation-timeoutMS
  • sessions-override-timeoutMS
  • sessions-inherit-timeoutMS
• Implement the following spec prose tests
  • https://github.com/mongodb/specifications/tree/master/source/client-side-operations-timeout/tests#9-endsession
  • https://github.com/mongodb/specifications/tree/master/source/client-side-operations-timeout/tests#10-convenient-transactions
